SABR - shaft design and analysis

SABR allows the user to model transmission shafts, from single section shafts for initial concept sizing to complex multi-node arrangements for full and detailed system analysis, quickly and accurately. 2D CAD can be imported and shaft profiles built up with simple click and drag on the overlaid CAD making complex shaft building trivial.

Stress concentration factors are automatically calculated and can include oil holes, circlip grooves and fillet radii at changes of diameter. Material properties are combined with automatically calculated size and surface finish factors for use in fatigue analysis. The results are plotted on a Haigh diagram using the modified Goodman criteria to give safety factors at every location against infinite life.

• Interactive 3D Graphical User Interface
• Ability to assess all levels of shaft complexity using 2D profiler with simple click and drag and overlaid imported 2D CAD
• Automated stress concentration, size factor and surface finish factor calculation
• Haigh diagram plots of every location and tables of stress and safety factor. Colour plots of stress and fatigue safety factor for quick identification of critical areas
• Tabulated and graphical results showing breakdown of all stresses
